Lam 'P.m1v0..89,861, dated M04] 11, 1869;

comma STOVE-LID m'nnmnit l .The Schedule referred to in these Letters Patent and makin part of the name.

invented a new and improved Combined Stove-Cover and Damper; and I do hereby declare that the follow ing is a full, clear, and exact description thereof, reference being hadto the accompanying drawings, forming a part of this specification, andto the letters of reference marked'thereou, in which Figure 1 is a perspective view ofa stove-cover, having apart of my invention attached to it.

Figure 2 is a 'plan of the top of a stove, having my invention applied to it.

- Figure 3 is' a perspective view of a stove, having my.

invention applied to it. v

Similar letters of reference indicate like parts in all the figures.

To enable others'skilled in the art to make and use my invention, I will proceed to describe its construction and mode of operation.

A designates a segment of a circular rim, which is attached to the under side, of a stove-cover, as shown "infig'.1.m

Said rim A is .made of a portion of a circle, whose diameter is equal to thatof the. hole in the top of the stove in which it is to be used. The reason of this will be seen when we consider that the rim A, on the underside of the stove-cover D, must set as close to the edges of the side flue-strips O O, and centre fluestrip B, as is possible, in order to shut oft all or a portion of the back-draught of the fire whenever required. The depth of the rim'A must be such as to nearly touch the top oven-plateH, when the'cover D is in its place on the top of the stove.

(J designates flue-strips, set against the sides of, the

stove, and extending to the edge of the stove-holes, as shown in figs. 2 and.3.

r B designates a central flue-strip, placed between the two back holes of the stove shown in fig. 3, and extending to the edges of the holes, .as shownin the same fi ure. Flue-strips O O and B, may be curved, as shown in the accompanying drawings, or they may be made straight, and set at such an angle as to conduct easily the products of combustion from the fire-pot of the stove toward the-.exit-flue of the same.

'lhecircular segment A may be attached tothe under side of a circular ring, such as is used in many stoves to reduce the size of the hole for smaller utensils, and if constructed in this manner, it may be operated by a cover having a stop or catch by which to move the ring around with-the cover, or it might be moved or operated independently of the cover but I prefer to have the rim A attached to the cover D, as shown in figs. 1 and 3. I d It will be seen from the above description, that whenever the covers D are turned so as to bring their rims, A, directly across the openings between flue-strips O and B, (as shown on the left side of figs. 2 and 3;) that then all communication with the direct draught of the stove will be cut off, and if the stove is provided with front-descending lines, as shown in figs. 2 and 3, that the products of combustion will all be forced to pass down said fines, as shown at f; on the left side of figs. 2 and 3.

When it is, wishedto have all the fire pass toward one of the holes, then the covers D are turned, as shown in fig, 3, in which A designatesthe rim of one cover, as turned to one side, leaving the flue between B and G, on the right side of the stove, wide open, the rim A of the opposite cover being turned, so as to shut off or close all communication on that side of the stove with the direct draught; then it will be seen that nearly all the heat from the fire will he concentratedv on theright side of the stove, as shown in figs. 2 and 3.

It will also be seen that, by means of v the two dampers A, as above described, I can regulate, to any degree required, the intensity of the direct draught of the stove in which my inventionmay be used, thus enabling me to restrain the rapid combustion of fuel, and thus to retain the fire for a longer period of time without the necessity of frequent additions of fuel thereto.

What I claim as new, and desire to secure by Letters Patent, is-.

The construction ofa stove-cover, having a. circular rim, A, attachedto its under side, in combination with flue-strips O O and B, or their equivalents, substantially as herein shown and set forth. i
